Michael Schurter ed77c0944b DRY up restart handling a bit.
All 3 error/failure cases share restart logic, but 2 of them have
special cased conditions.

Michael Schurter 73fb71ca10 RestartDelay isn't needed as checks are re-added on restarts
@dadgar made the excellent observation in #3105 that TaskRunner removes
and re-registers checks on restarts. This means checkWatcher doesn't
need to do *any* internal restart tracking. Individual checks can just
remove themselves and be re-added when the task restarts.

Alex Dadgar 07ed83fdd5 Non-locked accessors to common Node fields
This PR removes locking around commonly accessed node attributes that do
not need to be locked. The locking could cause nodes to TTL as the
heartbeat code path was acquiring a lock that could be held for an
excessively long time. An example of this is when Vault is inaccessible,
since the fingerprint is run with a lock held but the Vault
fingerprinter makes the API calls with a large timeout.

Alex Dadgar fd7d614ae4 Handle interfaces that only have link-local addrs
This PR changes the fingerprint handling of network interfaces that only
contain link local addresses. The new behavior is to prefer globally
routable addresses and if none are detected, to fall back to link local
addresses if the operator hasn't disallowed it. This gives us pre 0.6
behavior for interfaces with only link local addresses but 0.6+ behavior
for IPv6 interfaces that will always have a link-local address.

Fixes https://github.com/hashicorp/nomad/issues/3005
